It has been engineered to house a Ford V8, although other customer installed options are available. Crucially, the Series 2 will be sold in component form.

The sub 1300kg car, courtesy of an all-aluminium monocoque, was originally rated at 310bhp owing to its naturally aspirated 4.0-litre V8. But a supercharged option boosted that to 450bhp. A total of 249 were built.

Built in conjunction with Wingard Motorsports, Series 2 owners can choose from either aluminum, carbon fibre or titanium bodies. It is 12% lighter and its stiff chassis is capable of handling 800bhp according to Shelby.

CEO of Shelby American Joe Conway said: ‘Carroll always intended for that innovative chassis to be the first in a line of modern sportscars, which is why he called it the Series 1. The new Shelby Series 2 is the evolution of that minimalist car, offering breathtaking performance in a modern two seat roadster.’

Shelby’s American president Gary Patterson added: ‘While the Shelby Series 2 is based on the first-generation car, it’s a significant leap forward.

‘It blends old school craftsmanship and current technology, pushing the roadster into super car territory. It is the perfect car for collectors and enthusiasts globally who want the ultimate in exclusivity and to be completely engaged with the driving experience.’

The fastback-style Super Snake will be limited to just a 10-car build and each will include an original VIN plus signature from Carroll Shelby and Don McCain who spearheaded the original programme.

All will use 1967 Mustangs as donor cars with the 427 cubic inch V8 producing 530bhp. Capable of 170mph, the original prototype sold most recently for $1.3million. This time around, each car will cost just shy of $250,000.
